2 Claims. (Cl. 58-43) This invention relates to horological instrudesired position for indicating the location of a ments and particularly to an improved comship, city or other point.

However, it will be 95 Figure 4 is an enlarged fragmentary perspecevident that the pinion 29 might be connected 35 tive view of an indicating bar and certain assoto the minute shaft or to some other shaft of ciated parts; the clock 28 so as to be operated by the clocks Figure 5 is a perspective view ai' the central mechanism at a constant speed. It will also be part of the bar shown in Figure 4, with a sliding understood that the various parts just described pointer mounted thereon; are properly proportioned so that when the 40 Figure 6 in an enlarged fragmentary sectional pointer I5 on bar 9 is stationary, the various view through Figure l, approximately on the numbers 30 on belt I6 will pass the pointer at line 6 6. intervals of. one hour.

Referring to the accompanying drawings by As illustrated in the drawings, the belt or numeral, I indicates acasing of any desired kind tape I6 is of a length to show the hours for 45 for enclosing certain parts of the device, said three days, but through the opening 2 the hours casing having an open face as indicated at 2 so for only one day are disclosed. As illustrated as to expose the map 3 which is secured by adparticularly in Fig. 1, the dark portion 3| indihesive or otherwise to a suitable back board 4 cates night time under all conditions, and as carried by the casing I in any desired manner. illustrated the belt or tape I6 moves to the left 50 At the top and bottom of the opening 2 there so that, as shown in Fig. 1, it is about 4.30 A. M. are provided rails 5 and 9 for accommodating in New York. As the dark zone 3| begins to pass the tubular portions 'I and 9 of the slide bar 9. the point 32, another dark zone begins to emerge On the slide bar 9 Is arranged a short sleeve In from behind point 33. The belt I6 is provided having a pointer II adapted to be moved to a with graduations and other indications for three days, but it is evident that a longer belt could be used without departing from the spirit of the invention, namely, a belt having proper indications for four or five days, though a belt for two days would not be practical. If desired the belt could be made from celluloid similar to the belts commonly used in moving picture machines, so that the various apertures I1 may be properly formed.

As shown in Fig. 2 the chain 25 passes over the sprocket wheel 2i which is rigidly connected to the gear wheel 26', which gear wheel in turn meshes with the pinion or small gear wheel 29 as above mentioned. 'Ihe gear wheel 29 is connected to the mechanism of the clock 26, and the gear wheel 26' is carried by the casing of the clock, so that when the clock is secured by suitable sprockets 34 to the casing or housing I, all the parts will be held in proper position for functioning accurately. The clock 28 may be an ordinary spring clock, electric clock or some other form of clock without departing from the spirit of the invention, but it must be of a size to have suiiicient power to move the various parts as mentioned. The parts are compartively small and light and consequently a small amount of power is all that is necessary, but this power must be enough to cause the parts to move at constant speed day and night.

As illustrated in Fig. l the map 3 is a flat map of the world and may be provided with the necessary details such as indications of cities, paths for ocean going ships, and the like. When the clock is in ordinary use the bar 9 is merely left in any desired place and the belt I5 continues to move at all times. The bar 9 may be moved at any time in order to secure the time of day or night at any point on the earths surface, the same being reckoned from a given point as, for instance, the Greenwich line. As shown in the drawings, New York is a certain distance west of Greenwich and consequently when the pointer II is moved to the dot on the map indicating New York, the pointer I5 will indicate the time of day at New York. If the bar 9 was then moved quickly over so that the pointer II pointed at Greenwich, the pointer I5 would indicate the time at Greenwich, namely' 9.30. If the pointer II was then quickly moved over to the Hawaiian Islands the pointer I5 would indicate the time at these islands, which as shown on the drawings would be 1l P. M.

By reason of this construction a person in New York can tell the time of day or night at any place on the globe and, consequently, will know whether is is possible to telephone to any distant point with hopes of finding the desiredparty near the telephone. As an example, if someone in London, England, wishes to telephone to a person in New York, and it was 9 A. M. in London, the English party could move the bar 9 until the pointer indicated New York, which would show that it was then 4 A. M. in New York. Consequently the English party would defer telephoning to New York until such time as he knew the New York party would be ready to receive his message. In locating ships on the ocean the same idea may be carried out.

I claim:-

A geographical clock including a housing having an opening in one face, a board positioned in the housing and supported near the front thereof, a iiat map of the world carried by said board and exposed through said opening, a top bar extending across said opening at the upper edge of said map, a bottom bar extending across said opening at the bottom of said map, a slide bar connecting the top and bottom bars, said slide bar at the respective ends having encircling sti'uctures for loosely encircling said top and bottom bars whereby said slide bar may freely slide back and forth over said map, s pointer slidingly mounted on said slide bar, a pointer carried by the slide bar at the upper end and projecting above said top bar, an endless tape positioned to travel across said opening immediately above said top bar, said last mentioned pointer projecting over the tape, said tape having sets of numbers and graduations indicating hours and parts of hours of several days, twentyfour hours being disclosed in said opening at all times, and clock mechanism connected with said tape for driving the same at the proper speed.

2. A geographical clock including a housing having an opening in one face, a map of the world carried by the housing and exposed through said opening, a top bar extending across said housing adjacent the upper end of said map, a bottom bar extending across said housing adjacent .the bottom of said map, a slide bar slidingly mounted by said top and bottom bars so that said slide bar may freely slide back and forth over said map, a pointer slldlngly mounted on said slide bar, a pointer carried by said slide bar at the upper end, an endless tape positioned to travel across said opening and near said last-mentioned pointer, said tape having sets of number and graduations indicating hours and parts of hours of several days, twenty-four hours being disclosed in said opening at all times, and clock mechanism connected with said tape for driving the same at the proper speed.
